Swami Vivekananda (January 12, 1863 – July 4, 1902) was one of the most famous and influential spiritual leaders of the philosophies of Vedanta and Yoga and a major figure in the history of Hinduism and India. He was the chief disciple of Ramakrishna Paramahamsa and the founder of Ramakrishna Math and Ramakrishna Mission.

While he is widely credited with having uplifted his own nation, simultaneously he introduced Yoga and Vedanta to America and England with his popular lectures and private discourses on Vedanta philosophy. Vivekananda was the first known Hindu Swami to come to the West, where he introduced Eastern thought at the World’s Parliament of Religions, in connection with the World’s Fair in Chicago, in 1893. It was there that he was catapulted to fame by his by wide audiences in Chicago and then later elsewhere in America.
